Wow, exciting times! congrats

The reason I want to maybe finish earlier is so that we can get settled in the new house before bubby comes along and before I get too big to be able to do a single thing.
I agree, if you are wanting to 'get things done' it might be worht finishing up a bit earlier.

I worked admin-type job until 38.5 weeks, then at home until 41 weeks - in hindsight, waaaay too long on both counts, I had forgotten how tired you get at the end...

Good luck
